In the morning, boarding the huge ship that was the same size as the mainstream warships of later generations, Zhu Yuan suddenly realized.

Yourself is systematic.

I also have an old grandfather.

These two are both called 'Zhu Yuanzhang'.

Lao Zhu is so good to himself, so good that while he begins to be grateful, he will inevitably feel guilty about his hypocrisy, but it is impossible to confess.

will die.

Moreover, not only this big ship with the same length as at least ten buses in later generations, but also Zhao Xu and Zuo Qi brought two thousand elites to act as Zhu Yuan's personal guards, just a series of edicts the day before.

Personnel aspects.

For example, Mao Xiang, who was transferred from the Northern Expeditionary Army to serve as the commander of Jiaozhou Wei, the former first commander of Jinyiwei, can be said to have escorted Zhu Yuan all the way before to get this errand.

There are also generals Si Shaoqing and Huai, who have discussed several times before because of the matter of Zhu Yuan's family repairing the garden.

Lao Zhu asked about the personnel arrangements in Jiaozhou, and Zhu Yuan remembered that he and Huaitou talked about how to build houses by the water to make them stronger, and so on, it should be no problem to repair the harbor, so he recommended the other party.

He Huai changed from being a secretary to a state prefect.

Although it is a flat tone, it has not been promoted from the fourth grade to the third grade like Mao Xiang, but with the background of Hehuai, a craftsman in Chuzhou, more than ten years ago after joining the army, with his craftsmanship and his own qualifications, he has survived step by step to the current position, because he is only barely literate, and if he lacks special opportunities, it is difficult to rise again in this life.

This flat adjustment can be regarded as crossing a big threshold.

Do a good job, continue to improve, and it is not impossible to even be listed in the middle book in the future.

Anyway...... Yesterday when he got the assignment, He Huai came to Houhu again with an excited face, and helped Zhu Yuan to consult how to repair his mansion on the lake without saying a word, and forcibly kowtowed to Zhu Yuan before leaving, making Xiao Zhu feel that he had been robbed of his life for a few more days.

There is also Jiaozhou, which has just been established.

According to the plan, the grain ships were transported from Mingzhou to Jiaozhou, and then they could turn to Jinan through the inland canal, and then enter the Yellow River channel and be transported to Bianliang.

Because it was the destination of the maritime grain route that Zhu Yuan had recently determined, it was able to be transferred from the county to the state.

also added a Jiaozhou guard.

Of course, Lao Zhu must also be able to see the strategic value of Jiaozhou Bay for a long time in the future, so he will agree.

All in all, Xiao Zhu is responsible for making a wish, and Comrade Lao Zhu, the 'system' and 'grandfather', is responsible for realizing it, and the whole process is green.

A green light is not enough.

Regarding the edict on transporting grain, it is obvious that Hua Gao is the number one, and Zhu Yuan is just an 'assistant'.

That is to say, this shipping errand is done well, Zhu Yuan must have credit, messed up, the black pot is the number one, and the number one is called Hua Gao.

This protection is too obvious.

Zhu Yuan can also understand Lao Zhu's hard work, this is his first errand, if he messes up, he will completely take the blame, what he wants to do in the future, even if Lao Zhu can be arbitrary, after all, he still has to consider the thoughts of the ministers.

After all, there are rules in the court, and the most taboo rewards and punishments are unknown, and there is no distinction between merit and demerit.

Let Huagao be the leader, fail, there will always be an explanation in the future.

Obviously, Lao Zhu is still not optimistic about shipping, this is not speculation, inexplicably Hua Gao, who has changed his attitude towards Zhu Yuan and is more flattering, got on the ship and said, if you can't do it, you can't do it, don't worry too much, keep it at ease, and wait a few months for us to transport the grain to Zhenjiang.

A pair of righteous and thin clouds that I have carried down the black pot.

This......

In fact, thinking about Lao Zhu getting that information, he often drifted more than 30%, Zhu Yuan still doesn't believe it, but he hasn't gotten the relevant information recently, but in short, Lao Zhu still thinks that the river transportation is more secure, even if it is slower.

As for some things that happened in the north because of the lack of food, the emperor always had a choice.

However, Zhu Yuan's mind was always haunted by the dishes and faces he saw the day before yesterday, and he always remembered the sentence that he said when he knelt on the ground and was worried that he would drive her family back to Shandong.

Gratitude and guilt for Lao Zhu, and uneasiness about the situation in the north, made Zhu Yuan start his work after the big ship was stable, and did not hide in the luxurious and comfortable cabin specially prepared for him.

A total of seven floors of cabins, up and down, front and back, Zhu Yuan walked through.

In the end, I really wanted to go up to the lookout on the mast to have a look, but I was resolutely stopped by Hua Gao, and I had to give up as if I was forced to die.

The conclusion is that there seems to be nothing to do on his own.

Such a big ship, what Zhu Yuan could think of, the ancients also thought of, and what Zhu Yuan couldn't think of, the ancients also thought of.

Fire prevention, you say?

There is a complete set of processes on board, there is water, sand, and wet cloth.

You say lifesaving?

There are lifeboats on board, as well as life jackets designed by the ancients.

You say that this is a hard sail, but the soft sail used by people for great navigation is advanced!

!

At least under the existing conditions, Zhu Yuan could not find a place to play on the giant boat under his feet.

It's not that it's not without ideas.

Want to press a steam engine......

Spit!

It's still going to be one step at a time.

Let's go back to what is going to happen itself, transporting grain.

These days, reading all kinds of materials and asking all kinds of people, Zhu Yuan has roughly had his own ideas.

Is it feasible......

Again, step by step.

In the evening, the flotilla anchored in Jiangyin.

In fact, it is no problem to sail overnight, so that you can get to Taicang tomorrow morning, and if you are lucky enough to encounter a tailwind, you can arrive in Mingzhou tomorrow evening.

Huagao firmly disagreed.

Zhu Yuan made half of the compromise, and the other half didn't get off the boat, not wanting to toss this small Jiangyin city anymore, after all, there were more than 20 ships and more than 3,000 people in this line, and it was a big bustle up and down.

Zhu Yuan didn't let people get off the ship, which can be regarded as military training.

After all, many people on this ship will go to sea in the future, and they should not want to dock for as little as ten days or more than a month, so they should be familiar with it in advance.

By the way, test the instrument that has just been built.

Astralizer.

Zhu Yuan's name.

Those who are familiar with ancient seafaring have probably heard of the art of astrology, which is simply to measure the angle of the North Star to confirm the latitude. The ancients did not necessarily have the concept of latitude, but they also knew that the angle between the North Star and the horizon was different at different locations.

The traditional star-pulling equipment, called the star-pulling board, is six large and small wooden boards, holding the wooden board and stretching out the arm for comparison, which one is on the North Star, which is probably the result.

It's rough to think about.

Knowing the principle, Zhu Yuan's recently designed star-pulling instrument is actually very simple, a three-foot square wooden board base, on which an observation copper tube only the thickness of a fountain pen is installed, which is used to observe the North Star. The copper tube is connected to follow the rotating pointer, and next to the pointer stands a semi-arc scale of 0 to 90 degrees, which is actually a vertical plate, with a radius comparable to the base of a square plank, because it is large enough, and the scale is very fine, so that it can reach 0.1 degree.

In addition, the four corners of the wooden base are equipped with levels, which are the kind that later rely on the principle of liquid leveling to ensure that the base is level. In fact, the level also appeared very early, it is not a new thing, and it is recorded in the "Mengxi Writings" that Zhu Yuan has read these days.

God cooperates, tonight is a sunny day, and the sky is full of stars.

This observation not only attracted the entire fleet of civil and military officials who were slightly on the stage to watch, but also set up a perimeter guard to strictly prohibit idle people from approaching. A group of people seemed to be about to perform some mysterious sacrifice.

It's true that no one thinks this is a normal thing.

is like Liu Lian, who is a 'family scholar', when he sees the globe during the day, his eyes are ...... It seems that termites have seen a large piece of wood, and Zhu Yuan is really afraid that he will gnaw on it.

The same goes for this telescope.

Because according to the theory given by Zhu Yuan, if the star guide is really useful, it can measure the distance from Mingzhou to Jiaozhou relatively more accurately.

Very simple.

The diameter of the earth is 80,000 miles, and every latitude is about 222 miles, not to mention, this star tractor is also accurate to zero tenths of a degree.

Although the error of this algorithm is very large, there is a longitude deviation, and the earth is not a standard circle, but it is more than enough to overturn the current statement that thousands of miles of sea routes are often taken.

How can it be thousands of miles away?

Zhu Yuan remembers a sentence that fear comes from the unknown.

The ocean is so big that there are so many unknowns that people are afraid to explore it for thousands of years.

Now, if the sea is no longer so mysterious, it will no longer be so prohibitive to explore the ocean. This is also the reason why Zhu Yuan worked day and night to make the globe.
